' =-Application March-1.6, 1943; Serial No.479g363 V '3 Claims.

This-invention-relat'es to pliers, andit is pri- -marily an object ofthe invention to provide a tool of this kindwhich can be usedtoparticular advantage in out-of-the-way, places or in'extremely-difiicult positions as. is often encountered in working onairplanes 'and *the modern automobile.-

It--isg also an objector-the invention to providepliers of along=nosedtype and wherein the jaws are angularly disposed with respect to theiraxes of turning movement.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved plierswhereby certain important advantages are attained, as will behereinafter more fully set forth.

In order that my invention may be better understood, I will now proceedto describe the same with reference to the accompanying drawing,wherein:

Figure 1 is a view in top plan of pliers constructedin accordance withan embodiment of my invention, with a portion broken away.

Figure 2 is a view, partly in side elevation and partly in section, ofthe pliers as illustrated in Figure 1.

Figure 3 is a detailed sectional view taken substantially on the line3-3 of Figures 1 and 2.

Figure 4 is a detailed sectional view taken substantially on the line4-4 of Figures 1 and 2.

Figure 5 is a fragmentary detailed sectional view of the inner extremityof one of the handles, and

Figure 6 is a sectional view taken substantially on the line 66 ofFigure 5.

In the embodiment of the invention as disclosed in the accompanyingdrawing, I denotes an elongated shank cylindrical in cross sectionthroughout the major portion of its length and which has integrallyformed with one end portion thereof the laterally disposed elongatedstraight nose or jaw 2. This nose or jaw 2 is disposed forwardly on apredetermined angle and preferably substantially 45 degrees.

The rear extremity of the shank I has a part 3 angular in cross-sectionand slightly tapered outwardly for tight fit within a socket 4 providedin the inner face 5 of a handle member 6. This face 5 is flat for closecontact with the adjacent end face I of a sleeve 8 surrounding the majorportion of the shank I. These faces 5 and I are perpendicular to theshank I and the sleeve 8. The face 5 at the inner end of the handlemember 6 is .provided with an outwardly disposed flange 9 arcuate fromone end to the other and which extends within an arcuate socket I0provided in the face I of the sleeve 8.

The flange 9 and the socket II] are concentric of theleng'th orthe'fiange 9. The outer or forward endportion of the sleeve 8hasrigidly'secured thereto a second straight nose or jaw II complementalto and coacting with the nose or jaw 2.

The rear portion of the sleeve 8 is provided with a handle member I2.This handle member I2 as well as the handle member 6 are so formed as tobe readily and conveniently grasped by the hand of the user and, as isillustrated in the accompanying drawing, said handle members 6 and I2are disposed upwardly and rearwardly on a predetermined angle orcurvature in a direction substantially opposite to the straight noses orjaws 2 and II.

The flat face 5, hereinbefore referred to, is provided, in fact, upon ahead I4 at the inner or forward end of the handle member 6 and is to theside of said head I 4 remote from the nose or jaw 2, whereas the handleI2 is at the side of the sleeve remote from the nose or jaw II.

While the handle 6 may be rigidly held to the shank I in any mannerpreferred, in the present embodiment of the invention and as 11-lustrated in Figure 2, the outer end of the portion 4 is provided withan extended rivet pin I5 extending through the rear portion of andbeyond the head l4 with its outer extremity up set, as at I6, in a wellknown manner.

From the foregoing description it is thought to be obvious that a,pliers constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and operated.

In the use of the pliers it will be readily apparent that when thehandles 6 and I2 are forced apart to the maximum extent permitted by theinter-leaved coupling comprising the arcuate flange 9 and the socket I0, the points of the jaws 2 and II will be separated as illustrated inFigure 1. This will permit the grasping of any object located in aposition which might not be accessible to pliers of the usual design andwhen such object is located between the separated ends of the jaws thejaws may be readily forced together into gripping relation by pressingthe handles together to rock the shank l in the sleeve 8. The handle l2and sleeve 8 together with the jaw II which is integral with the sleevemight be considered as remaining stationary while the other handle, theshank I and jaw 2 which is coupled with the shank, oscillate on thelongitudinal axis of the inter-connected shank and sleeve.

What is claimed is: V

1, Pliers comprising an elongated shank, a sleeve freely surroundingsaid shank, laterally disposed long jaws carried by the outerextremities of the shank and sleeve, a rearwardly disposed handle membercarried by the rear portion of the sleeve, and a rearwardly directedhandle member secured to the rear portion of the shank, said handlemembers providing means for relatively rotating the sleeve and shankabout a common axis, the rear-'porti0n" of the sleeve being providedwith an arcuate socket, the inner end of the handle of the shankbeing'provided with an ancuate flange extending within the arcuatesocket, said socket being ofa length greater than the length of theflange. '2. Pliers comprising a relatively long shank of circular crosssection, asleeve having the shank extending therethrough 'for turningtherein, a pair of jaws carried by the sleeve and shank at one end andextending obliquely of the sleeve and shank, a handle member carried bythe other end of the sleeve, a handle member carried by the other end ofthe shank, the handle members extending in divergent relation andsubstantially obliquely of the sleeve and shank in the oppositedirection to the jaws, and an interleaving coupling between the adjacentportions of the handle members limiting the relative turning of suchmembers on the axes of the shank and sleeve. 7

3. Pliers comprising a relatively long shank of circular cross section,a sleeve having the shank extending therethrough for turning therein,jaws carried by the outer extremities of the shank and sleeve andextending obliquely to the same, a handle member integral with the otherextremity of the sleeve, a handle member attached to the other extremityof the shank, the handle'members extending substantially obliquely tothe shank and sleeve in the opposite direction from the jaws, the handlemembers at their adjacent ends having opposing faces lying in'a planeperpendicular to the shankand sleeve, one of said faces having anarcuate slot therein concentric with the shank and sleeve,-and a membercarried by the other face and slidably engaging in the arcuate slot, theslot and the member engaged therein functioning to limit the relativeoscillatory movement of the handles.
